Grayscale stated that "the recent rise in Zcash (ZEC) prices has significantly increased mining profitability, leading to increased mining activity and strengthened network security. According to Wu Blockchain, Grayscale said, "The mining reward obtained by one Zcash mining device per day is about twice that of a Bitcoin mining device. Based on power efficiency, the profit per megawatt-hour (MWh) is about four times that of Bitcoin. However, the equipment used for Zcash and Bitcoin mining are not mutually compatible. Therefore, these figures are not a comparison of identical mining rigs." They added, "Based on standardized hashrate, total Zcash mining activity is estimated to have increased by more than 2.5 times this year. This situation has the potential to create a virtuous cycle."
